Q: What's the 6102 specification for deep groove ball bearings?: Deep groove ball bearings 6102 new code 60022RS, old code 180102, inner diameter (mm):15, outer diameter (mm),:32 width (mm),:9, weight (KG):0.026, price about 3 yuan

Q: Deep groove ball bearings are how to assemble, I feel there is no way to assemble ah!: Press in. All right, deep trenches and shallow trenches.

Q: Deep groove ball bearing 629Z code, how to resolve?: This is miniature bearingIron dust coverPrice is about eight or nine hair

Q: Angular contact ball bearings or deep groove ball bearings for vertical motors. What is the minimum motor noise?: If installed properly, the deep groove ball will be less noisy! Angular contact bearings have much better bearing capacity!

Q: How to select the sealing form of deep groove ball bearings?: The dust cover is metal and is suitable for use with high ambient temperature.

Q: There's a lot of trouble with the production process. We have a lot of rings and other accessories here. And the assembly. The so-called assembly, that is, the acquisition of rings and various accessories. Assemble the finished bearings and sell them.I think the process should be like this. Start with the ringRing: cutting plane and centerless grinding - zetoms hole chamfering -- dredging completed after heat treatment are then sent to the bearing factory.Bearing factory: automatic ring grinding (131201143 model) - ultra fine - cleaning ring - Union - pressure cage - cleaning product bearings - plus grease - gland - rust proof oil - Packaging - delivery: To know the production process, we should first make sure that the micro bearings or large and medium-sized bearings. According to your procedure, should belong to the small class.Ferrule factory:1., blanking (points bar material, pipe material, separate type)2. plane grinding and centerless grinding3., zetoms chamfer hole, dustproof groove4. heat treatment, tempering (some passivation treatment)The above procedure must be checked for size, deformation and allowance.Finish machining:1. plane mill (end dimension, parallel difference)2. centerless grinding (size, roundness, ultra precision, roundness)3. automatic grinding (131 size, roundness, roughness). 143 size, roundness, roughness. 201 aperture, taper)4. ultra fine (roundness, roughness, finish)In fact, there are still some processes

Q: What's the difference between the rubber cap and the iron cover of the deep groove ball bearings?: Iron cover only dustproof, waterproof rubber cover, dustproof and waterproof

Q: What does "deep groove ball bearing suffix" "MA" mean?: In FAG bearings, the MA represents the brass solid cage and the outer ring guides

Q: In the new standard, deep groove ball bearing type code name is 6, but I often see 16 to start with deep groove ball bearing code, such as 16005, I don't know what this 16 finger meanIn the mechanical manual, 16005 and 6005 are the same in diameter and outer diameter, but the bearing width is different. I just don't understand. What do you mean by 16?Isn't there a width code in the bearing model? And most of the bearings in the introduction, only that 6 represents deep groove ball bearings, need not appear 16 this code. But I checked, someone said, "16" means deep groove ball bearings which can be subjected to greater axial force. I wonder if it is?: 6 and 16 are deep groove ball bearings code, the difference between the two is bearing width, that is, the thickness of the points, and the rest of the same size

Q: How is the deep groove ball bearing fixed?: Landlord or a body sketch it, this is not good answer. Generally speaking, the fixed outer ring or inner ring can not simultaneously fix the outer ring and the inner ring.
